Lack of sleep may increase the risk of Alzheimer's disease

Swedish researchers selected 15 healthy men with an average age of 22 and a normal weight, who usually maintained seven to nine hours of high-quality sleepThe results showed that the average amount of Tau protein in the blood increased by 17 percent after the subjects were deprived of a night's sleep (sitting in bed in light, playing games, watching movies or chatting), while the average Tau protein in the blood increased by only 2 percent after a full night of sleepA pathological change inAlzheimer's patients is excessive phosphorylation of tau protein in the brain, which accumulates in cells to form a neuronal fiber entanglement, which is closely associated with nerve cell death and cognitive dysfunctionPrevious studies have shown that older people have increased tau protein levels in their cerebrospinal fluid after sleep deprivation, and head trauma also increases Tau protein levels in the bloodco-author Jonathan Sedness of uppsy apron in the blood may mean an increase in tau protein levels in the brain, but it may also be that tau protein seroted from the brain from the brain, so further research is needed to determine whether irregular sleep increases the risk of Alzheimer's disease, said co-author Jonathan Sedness of upmarket in The University of Uppsala in Sweden.
